About PDF Merger
Combining multiple PDFs into one is a daily task for anyone who works with contracts, reports, or scanned documents. This merger uses pdf-lib loaded in your browser to copy all pages from each uploaded PDF into a single output document in the order they appear in the list. Upload PDFs by clicking the upload zone (multiple files at once supported). Each file appears in a list with an X button to remove it. The Merge button is enabled only when two or more PDFs are loaded. The merged PDF is downloaded directly to your device. Because pdf-lib runs entirely client-side, your files never leave your browser — no cloud service, no size limit beyond your device's available memory. Lawyers combining contract exhibits, accountants merging monthly reports, and students assembling research papers are the primary users.
